Partitioning - Created A Partition And Can't Boot
Oct 20, 2009
I put a clean install of Win 7 onto my laptop and all was well. I went into disk management and shrunk my C: partition a bit to create a new partition.
Having done that, I now cannot boot up. It would seem that something I've done has caused the system reserved partition to become my C: drive and what was C: is now D:! Windows 7 attempts a repair when I boot up, but this fails due to a corrupt registry.
I've put the disk back in to see what that offers and it's here that I noticed that Windows is now on the D: drive. Opening a command prompt confirms how the drive letters have been reassigned.
I'm not 100% sure but assume that it's trying to boot from the system reserved partition and not liking it? I only just installed yesterday so don't mind doing a reinstall if that's the easiest fix, but just wonder if anyone knows what I can do to ensure this doesn't happen again? I presume my partitioning shenanigans are to blame somehow?

I created a new partition, and accidentally made it my primary partition (C: being my primary one and D: being by other one) now whenever I boot up I get NTLDR missing ctrl+alt+del to restart. So I downloaded the windows 7 repair files from one website and tried to fix it, but I failed and now I wanted to know is there any other way I can fix using command prompt or will I just have to reinstall windows 7.

I reinstalled Windows recently, but it used the same boot partition from my old installation. I got rid of the old partition (it was on the wrong hard drive) and created a new one with the repair disc. Windows boots, but won't install updates. Bcdedit outputs The boot configuration data store could not be opened. The system cannot find the file specified.

I created a 20gb partition on my external hard drive and no longer require the partition. It is currently unallocated space so I want to format it into NFTS. Using computer management the partition was selected and and I went through the steps to format but i keep on getting an error message saying there is not enough space on the disk to complete this operation.

When originally installing Windows 7 Ultimate I noticed it created a 100mb system reserved partition. No probs.
Recently I turned on AHCI in my bios and attempted to do a clean install. This time WinPE did not create a reserved partition and despite creating an 80gb partition to install windows on it said “Setup was unable to create a new system partition or locate an existing system partition.”
Install refused to proceed any further, pointing me to some log files I could not find. I booted from my repair disk and tried to make the partition active, which was already marked as active and tried again. No luck.
I had deleted all partitions on the drive.
So I turned off AHCI and tried again. I missed the "press any key".. and system complained about a "Master boot record error".. I rebooted and tried to do install again. Same issue.
I was able to recover my system from an image I created earlier, but I sure would like to know why the reserved partition was not created, and why windows refused to install. Because I'm going to try again.
I have purchased a new HDD, one that is supposed to be much faster than my old one, which of course has not been formatted. I tried that drive with and without AHCI and had the sasme issues.

I created a new partition upon a brand new Win 7 install. I have a 750 gb HD. Out of the 750, I created a 100 gig partition for the OS (or so I thought). Windows installed just fine, however, My Computer only sees the 100 gig partition, where the windows was installed. I should roughly have 650 gigs left, on a different partition but it is nowhere to be found.
What are my options? This is my first Win 7 install. Do I need to reinstall from scratch? I remember with Win XP it was so easy to create partitions upon new installs.

This is quite a long story, So let me get straight to the point.On my Dell Optiplex 360 Computer (Windows 7-Ultimate) I partitioned the hard drive to make space for another windows installation. I then installed Windows Vista Ultimate on it.All of that went successfully but after a while it became useless for me and my computer.

I intend to rebuild my system shortly, mainly reformatting/partitioning my drives. Full system wipe, nothing less will do... Spring Cleaning.
My goal is to have a small Vista partition as a safety net, and optimize my configuration to use Windows 7 as my main OS. I have 2 640gb hdds, one with a 16mb cache, one with 32mb. Both sata and in no sort of raid.
After researching partitioning theory (people take it seriously!), I'd like to try and take advantage of the outer edge of my hard drives, giving my os and page file faster access times.
However, I am unsure of how much control I will have over partitioning my drives from scratch. I would like to assign the following partitions, beginning at the start of each drive (the outside edge):
hdd1(16mb): :/pagefile for windows 7 ~4gb; c:/Vista ~32gb; ...
hdd2(32mb): q:/Windows 7 32~64gb; ...
1. Will this give me any problems? particularly having the first hard drive contain the page file partition before the active system partition?
2. I've read elsewhere windows creates itself a 200gb partition on fresh install, is this forced?
3. Install Vista then Win 7, then which hard drive should I point my bios to for the boot loader?
3a. Assuming I install linux in the future, would I then need to point bios to the drive I put linux/grub on?
other details: running a nVidia 750i mobo with pretty good bios, perhaps providing more flexibility when it comes to boot? Intel core 2 and all that.

I'm a long-time reader but new poster. I am currently running Windows 7. I want to install Windows XP onto another disc and have a dual-boot setup. I keep Windows 7 up to date and secure, but for the XP partition, I would rather not have antivirus running or even installed, in order to limit background processes. I will not be logging into any place or making any credit card purchases when booted into Windows XP. It will just be used for surfing, games, etc. Further, if and when XP becomes compromised or buggy, I will simply overwrite the partition with a backup image.
If I use Bitlocker to lock down the Windows 7 partition (with the encryption key on a thumb drive) and boot into Windows XP, am I correct in thinking the XP installation see or can't access the Windows 7 partition? If XP gets compromised, can a virus access or write to the Windows 7 partition?
Is there any other reason why this would not be secure? Can a virus write to the BIOS?

I have Windows 7 ultimate 64-bit installed on DELL desktop (Optiplex 990) i7 Core. I have two HDD: Disk 0 contains the operating system 500GB. and Disk 1 empty 1TB.
I want to make a partition on disk 1 to mirror the operating system partition and keep the remaining for data storage. I tried to do but I had the following error message: "All disks holding extents for a given volume must have the same sector size, and the sector size must be valid."
I tried to attach a screen shot but couldn't.

I have a Boot Camped Mac Mini with Windows 7. I recently needed to allocate more disk space to it as i only had a gig left, i booted into MacOS and used Disk Utility to make the Mac partition smaller, i rebooted into windows and downloaded software called 'Partition Wizard' from www.partitionwizard.com. I dragged the Windows partition all the way so that it used up all the Unallocated Space, it required a reboot to finsih and when it did it displayed an error such as thistatus:0xc0000255Info: The Windows Boot Configuration Data file is missing required informationI have the Installation Disk and i have tried repairing more than 3 times and it seemed to do nothing, so i tried using the CMD and bootrec.exe and now when i start the repair wizard it says there is no windows partition yet i can still try repairing things (Yet still does not repair anything). I downloaded EasyBCD but im on my Mac partition right now and its an exe, i have no clue how to run that within windows to try and repair the Bootloader. I do however have access to the BOOTCAMP partition through the mac side, and i can access all the files. Is there some way i can repair the bootloader through this?

System has XP pro and Vista installed, single hard drive (with 3 partitions, XP and Vista each on their own partition, 3rd partition is for data) Removed existing hard drive Installed brand new hard drive Installed Win 7 ultimate x64, works great Installed original hard drive (the one removed in step 2) So now, system has BOTH hard drives in it. Boot up, only XP/Vista boot menu appears (I can boot to XP or Vista, but not WIn 7) Also, when booting to XP with both drives in, the new drive with Win 7 shows up as Disk 1, with original disk as Disk 0.

I initially installed Windows 7 Pro 64-bit along side my Windows XP 64 bit on two seperate hard drives. What I'm trying to do is remove the drive that had XP on it and put it in my other system to do a fresh Raid 0 Windows 7 setup. But when I remove the XP drive, it wont boot into Windows 7. I'm fairly sure that Windows 7 rewrote the XP bootsector and so without that drive it wont boot. Can I recreate it on the Windows 7 drive?
I've tried the recovery stuff on the DVD, including all the command line tricks in the tutorials. When I go into the recovery mode, it doesn't even see my Windows 7 installation. However, in Command Prompt mode, i can browse into the hard drive, and see all the windows files.
What can I do without a fresh install?

I am new to windows 7. Recently i bought a laptop with windows pre-installed in it.
I have a HD drive of 500gb. Windows is already preinstalled on it. I Want to partition the drive without affecting any data. I loaded some 30 gb data already on the drive. I want to partition the 450gb drive into 3/4 drives each of 100gb, such that i can allocate the Os with a drive and remaining 2/3 with my personal data songs, movies...etc.
I want to partition the drive and I don't know how??? Can anyone please explain me step by step how to do it. The main point here is do i need to again reformat the whole drive such that before re-installing Windows 7 i can partition it (or) do i have any alternate solution such that while running windows I can partition the current drive without affecting any data other than system files.

I have a 2 partition disk split: C:Windows 7 & E:data . I want to sneak in a partition at the start of E: to hold XP os and thus "F:" becomes my new data partition. Shrink as far as I know will create a space after the currently existing E:. The added problem is I am only playing with a small drive and cannot just copy over the data.

I currently have Windows 7 64 bit installed in two partiions:C: drive and E drive. Everytime I start, windows from the C: partition automatically boots. How do I get the Windows from E drive to boot? Ultimately I'd like to use the windows from E drive (which has all my installed software) and delete the one from C: drive. The problem is that I installed the one on C: drive most recently. (Long story short, I tried to delete and old version of windows unsuccessfully, and had to unmount and reformat the partition.)When I go to System Configuration under the Boot tab, I only see Windows in one partition (C: drive), so it won't allow me to delete that.

My sister just got a new laptop with 7, then accidentally installed a friend's version of 7 on top of it, thinking it was Microsoft Office. I'm trying to restore to factory settings so she doesn't lose all the software that came with the computer.
I know the recovery partition is on the computer (I made it appear by assigning it a drive letter). But I cannot boot from it (or whatever I need to do to access it).
I have tried the following:
1) Advanced Boot Options -> Repair -> System Image Recovery: no system image
-> System Restore: no restore point
2) all possible F# keys at startup, including F10 which got me to Edit Boot Options, which seemed hopeful because it named the partition number, 3, but did not allow me to change it (the recovery partition is 2).
3) F2 -> setup (nothing there)
4) burning an iso of Windows 7 recovery disc, which just gave me the same repair tool as in the 1st attempt.
5) setting the recovery partition as "active" (in fact, I think it was already active).

I normally run Windows 7. Today I decided to try out Windows 8 as well. I went into Disk manager and created a partition. I then booted off of my Windows 8 DVD and installed it on that partition. Now, my computer is only booting into Windows 8. What I really want is an option to choose which OS to boot into, but I would really like to be able to get back to Windows 7.

So i had two partitions on a physical disk, and wanted to delete the first and enlarge the second. I usually use gparted off the ubuntu live cd because it completely separates itself from windows details and allows a lot of disk changes in one interface; no conflicts. I moved forward with my changes and rebooted the computerI now find myself standing at this boot screens with error 0xc0000225 and a "corrupt" /boot/bcd file. Googling that information, the first hit was a solution about using gparted and getting this error. I thought perfect, but going through the steps, i still have no resolve. I have now been in and out of every boot problem thread on the internet and cannot figure it out.I have tried: windows 7 repair startup tools- rebuilding the bcd from scratch- bootrec /fixmbr and /fixbootWhen i boot into ubuntu or repair mode, i can browse the file system fine. can see the /boot files, create a new bcd file, and so on. One thing to mention is every test i have tried yeilds the same consistent error. The error has not changed whatsoever. My assumption is not that the /bcd file is corrupt or configured wrong (as the gparted solution/post suggested)

I have two questions:
I am running Windows 7 dualbooted with WinXP, everything works fine. I want to get rid of the XP partition, and keep the Windows 7 one only, but there is a problem. THe partition on which XP is installed is set as system and active. I've googled around but I've found no easy solutions to this. Any ideas on how to do this without reinstalling the OS?
My second question would be about the Windows 7 update: I installed the 7100 build, when it got released, but as I saw now, the latest builds are like 7200+. Are the changes updated on my build somehow, or I would have to reinstall to have the new build?

I decided a week ago to install Ubuntu 11.04 alongside my Windows 7, which as you know, created a new parition. As you also know, Ubuntu likes to use it's own boot manager. Well, I decided that I was going to download and install the Windows 8 Build 7955 (as I found on Windows 8 Forums) onto the partition that was occupied by Ubuntu.. so, I downloaded the image and then, in my disk management, deleted the entire parition that Ubuntu was installed on. I went to restart my computer to finish an AntiVirus update shortly thereafter, and got a message saying something along the lines of "Grub error; unknown filesystem." I attempted a repair with my disc and nothing worked.Right now, I am installing Windows 7 on the new parition in the hopes that I can get it working again, just to get at my files on the main parition. If not, I do have a SATA-to-USB adapter that I can use to manually extract the files onto another computer, and then just wide the drive entirely, but I'm really hoping I don't have to do that, as it would be SUCH a nuisance if I had to re-do EVERYTHING on my laptop. So, what I'm asking is, if the fresh install on the new partition doesn't work, is there any way to restore the original boot manager, or am I kinda dead in the water?

I have Windows 7 on a Partition with 37.22 GB and Unallocated space with 37.31 GB. I want to extend the Windows 7 Partition to the Unallocated space. Is there any way to extend the current/boot partition? I tried diskpart but obviously that won't work I guess since I read later that you can't do it on the boot partition? Then how else are you supposed to do it?

I just recently installed windows 7 on a partition that previously had vista, and backed up my "users" folder on another partition. I copied all the files back to the 7 partition and used a program like partition magic to delete the backup and extend the 7 partition. my computer won't boot now. I've tried resetting the mbr, bcdedit, bootfix
